Is there a firewall running on that machine?

Is there a jcaLibrary.properties file that could be settings things for Java differently than the environment variables for the C utilities?

Hello Kay,

Thanks for the advice but setting the IP address did not help, I am just 
trying to access the variables on my own machine and have tried localhost 
and 127.0.0.1. I did try the logging method and saw at first I was not 
linking correctly to a shared library, but was able to fix the and no 
longer have the error. I don't see any error message about the PV other 
then it saying it is disconnected. I am attaching my log file to see if 
that might help. Thanks once again for the help.

Cheers,

Hi again:

Check the menu CSS/Preferences/CSS Core/EPICS for the auto addr. list and
addr list settings.

How do the settings compare to the EPICS_CA_*_ADDR_LIST environment
variables used by the command-line caget?

What if you de-select auto_addr_list and set the address list to the IP of
one of your IOCs? Do you then see the PVs on there?

What if you de-select auto_addr_list and set the address list to the IP of 
a
broadcast address that includes one of your IOCs?

Thanks,
Kay
